Execute UIC-541 standard, the power supply voltage of the anti-skid device host is DC48V or DC110V, and the operating temperature range of the equipment is -25 ℃ to+40 ℃

20 Host SWKP AS 20 C
Based on long-term experience in the field of vehicle microelectronics systems, the SWKP AS 20 C wheel slip protection system has been developed. This system can maximize the use of available adhesion during braking, thereby optimizing parking distance, preventing wheel lock (slip) and the damage it causes. The electronic unit of SWKP AS 20 C is housed in a small metal box. This metal box not only has good high-frequency shielding function, but also has strong impact and vibration resistance performance.

Speed sensor SWKP AS 20C
The sensor system of SWKP AS 20C is based on non-contact speed counting per minute. The SWKP IG 20 speed sensor ensures coordinated operation with the speed measuring gear, with a working clearance of 1.5 ± 0.5mm during wear free operation. A special feature of the speed sensor is its built-in optical multifunctional indicator light, which can be seen on the sensor housing. When SWKP AS 20C and 20R are turned on, the indicator light is on. You can see from the side of the track whether the wheel slip protection system is turned on or off.

Exhaust valve connection line
It is the linkage mechanism of the anti-skid exhaust valve, used on the connecting pipe between the air distribution valve and the brake cylinder, to transmit commands from the host, so that the host can control the exhaust and recharge of the corresponding brake cylinder. Adjusting the brake cylinder pressure to prevent axle slippage and determining whether the axle is slipping based on multiple slip criteria has higher accuracy and is widely used in locomotives and vehicles such as railway passenger cars and high-speed trains.

pressure switch
Used for automatic sensing of train pipe pressure. When the pressure exceeds the set pressure value, the power supply of the electronic anti-skid device is automatically turned on by triggering the pressure switch. When the pressure is lower than the set pressure value, the power supply is automatically cut off.

SWKP AS 20 R Wheel Slip Protection System
Execute UIC-541 standard, the power supply voltage of the anti-skid device host is DC48V, and the operating temperature range of the equipment is -40 ℃ to+80 ℃

Exhaust valve SWKP MV 20
The SWKP MV 20 exhaust valve is a two position three-way power solenoid valve. It is used to regulate the pressure of the brake cylinder during the braking process. Only when the pressure in the brake cylinder is at its optimal level can slip be prevented and the shortest parking distance be achieved.

Host connection cable and connection box
The 20C electronic anti-skid device is equipped with the following four types of connecting wires and junction boxes to achieve the monitoring and control capabilities of the electronic anti-skid device.


● OP optical connector input;


● RE relay output;


●MV electromagnetic amplifier;


● GE speed record.
